Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the Tiguan, depending on which brakes are affected.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Using a socket set, remove the lug nuts from the wheel.
Take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket wrench.
Carefully slide the caliper off the brake rotor and support it without stressing the brake line.
Remove the existing brake pads from the caliper bracket.
Check the caliper pins for lubrication; replace if necessary.
Install new brake pads into the caliper bracket ensuring they are seated properly.

5. Inspect and Replace Rotors (if necessary)

If rotors are scored or warped, remove the rotor by unscrewing the retaining screws (if present).
Clean the hub surface before installing new rotors.
Install new rotors, ensuring they are properly seated.

6. Reassemble Components

Reattach the caliper over the new brake pads and rotor.
Tighten caliper bolts to the manufacturer's specified torque (typically around 25-35 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Remove jack stands and carefully lower the vehicle back to the ground.
Tighten lug nuts to the specified torque (typically around 80-100 lb-ft).
